Recently I've starting seeing a few unwanted mailboxes mysteriously
appearing in my Mailboxes folder -- always empty, not names I recognize,
though I suppose they may have come from spam or junk emails that passed
by me too rapidly to be noticed.
Any way to block these, or any thing to look for that might be causing
them?
